I try to generate entities from database. What I do:
php console.php orm:convert-mapping --force --from-database annotation /var/www/test/src/test/Entity 
This command generate for me Entities class
Processing entity "ProductAdditional"
Processing entity "ProductSizes"
Processing entity "Products"
Entiti classes loks like:
<?php
use Doctrine\ORM\Mapping as ORM;
/**
 * ProductAdditional
 *
 * @ORM\Table(name="Product_additional")
 * @ORM\Entity
 */
class ProductAdditional
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;
    /**
     * @var string
     *
     * @ORM\Column(name="key", type="string", length=255, nullable=false)
     */
    private $key;
    /**
     * @var string
     *
     * @ORM\Column(name="value", type="string", length=255, nullable=false)
     */
    private $value;
    /**
     * @var string
     *
     * @ORM\Column(name="Type", type="string", length=255, nullable=false)
     */
    private $type;
    /**
     * @var integer
     *
     * @ORM\Column(name="product_id", type="integer", nullable=false)
     */
    private $productId;
}
In nex step I try generate entities methods with command:
php console.php orm:generate:entities /var/www/test/src/test/Entity
And get error:
Fatal error: Cannot redeclare class ProductAdditional in /var/www/test.ebay.gateway/src/test/Entity/ProductAdditional.php on line 14
What can cause my problem ? How to generate method for my entities ? I mean setter and getters .
